TIRE-REMOVER.

' To all w/wm zit may concern:

Be it known that I, Unns'rnn A. Ummt, citizen of the United States,residim at Kennett, in the county of Shasta and tate of California, haveinvented 0r liSHH'Bl't-ul certain new and useful Improvements in'Iire-Removers, of which the following is a specification, referencebeing bad therein to the accompanying drawing.

This invention relates to a (levire for removing and replacingautomobile tires, and Whi('l1 is also adapted to serve as a tirecarrier, and has for its object to provide a device of this kind whichis simple in construetion and convenient in operation so that a tire maybe quickly removed from and replaced on a rim. To this end the inventioncomprises a series of hooked arms or members adapted to be engaged withthe flanges ot' the rim and having swiveled eonneetions with shanksengaged by screw bolts which are in turn connected by links with hubsmounted on a svrew shaft having right and left hand threads and whichshaft may be turned to cause the said heads to rerede from or approachtoward each other. The screw-threaded connections of the said shankswith the screw bolts enable the hooked members to be adjusted in andout, by turning said shanks on said bolts, for use in connection withdifferent sized rims. The shanks-of the hooked members and their 0)erating parts just referred to are preferably inelosed in a twtrpartcasing which provides sleeves in which the. said shanks may move in andout radially. By engaging the hooked members with the flanges of a tirerim and then turning the 'srrew shaft in the proper direction the saidhooked members may be. drawn inward in such a manner as to contract a,split or jointed rim so as to enable a tire to be readily rei'novcdfrom or mounted on such rim.

In the accompanying drawing Figure 1 is a general view of the inventionwith the casing partly broken away, and Fig. 2 is a sectional view ofthe same. Figs. 3, 4, 5 and 6 are detail views ol certain parts of thedevice. I

Referring to the drawing, 12 denotes a casing part or housing preferablyformed in two parts of thin plate steel and having arms 13 bent at theircentral portions to scn iieircular form in cross section in each easmgpart, leaving side flanges which may Specification of Letters Patent.

be riveted together, thus forming radial sleeves. Hmtably supported inthe easing I2 is a shalt 14 having right and left hand threaded parts onwhich are mounted hubs in each having slotted projertions 16 t0 u'hu'hare pivoted the outer ends of links v1i: ointed at their inner ends tothe heads ol bolts 18. said bolts having srrmv [breaded shanks tapped intubes 19 mounted to slide eudwise in the sleeves aliordcd bv the ili'libl3. Mounted at the outer ends of the tubes l5), and having suirrledconnections therewith, are booked numbers 20, the books 21 at theopposite ends of said members being preferably reversely inclinedrelative to the length of said members. as more clearly shown in Fig. 6,so that they may be readily engaged with the flanges ot' a tire, hvturning them slightly on their swiveled bonnettions with the tubes orshanks 19 on \vhieh they are mounted, thus engaging first one of thebooks 21 with a tire flange and then engaging the other therewith.

In the operation of the invention the hooks 2i of the men'zbers areengaged with the flanges of a tire rim and the screw shank i4 is then.turned by applying a wrench to its squared cud H in surh a manner as tocause the huhs 15 to recede from each other, thereby drawing the boltsl8 and the tubes or shanks iii and hooked members 2" inward and thuscontracting a split or jointed rim in such a manner that the tire mayb4- readily removed from or mounted or plared thereon.

This removing and replacing device may be used as a rim and tire holderor carrier to be mounted on a vehicle, and to this end a support, as 22.may he connerted with the casing l2 by arms 23 attaehed to or integralwith said support and rasing, the support to be attached lo some part ofthe vehicle in any suitable manner.

The casing 12 may be provided with a door or rover 24 to Form a closureover the squared outer end of the screw shalt l4, and this door may heprovided with a suitable look so as to prevent unauthorized aroess tosaid squared end of said shaft and unauthorized removal of a tire fromthe device when used as a tire carrier.

Having thus dcsrl'ibed my invention I (rlaim and desire to secure byLetters latent:

l. A tire removing and 'rrplaoing and tire carrying deviee comprisin asuitable casing, a shaft mounted in suit? casing and having right andleft screw-threaded parts, hubs mounted on said screw shaft and inengagement withthel thre'adedparts thereof so as to move oppositely'endwise of said shaft when the latter is turned, links connected withsaid hubs, and hooked members connected to said links and adapted to bedrawn inward to contract a rim when a tire is to be removed therefrom orplaced thereon.

2. A tire removing and replacing and tire 'arrying device comprising a'suitable casing, a shaft mounted in said casing and having right andleft screw-threaded parts hubs on said screw shaft, links connected withsaid hubs, hooked members connected to said links and adapted to bedrawn inward to contract a rim when a tire is to be removed therefrom orplaced thereon, the connection of said hooked members with said linksbeing afforded by threaded bolts I to the heads of which the inner endsof said links are connected, and tubes slidable in portions of saidcasing parts and with which tubes said bolts have screw-threadedconnections and to the outer ends of which tubes said hooked members areswiveled.

, 3. A tire removing and replacing and tire carrying device comprisinga. suitable casing. a shaft mounted in said casing and having right andleft screw-threaded parts, hubs on said screw shaft and movableoppositely on said shaft when the latter is turned, links connected withsaid hubs, and hooked members connectedto said links and adapted to bedrawn inward to contract a rim when a tire is to be removed therefrom orplaced thereon, the hooks on said hooked members being reverselyinclined, as set forth.

4. A tire removing and replacing and tire carryine device comprising asuitable casing, a s iaft mounted in said casin r and having right andleft screw-threaded parts, bubs on said screw shaft and movable endwiseof said shaft when the latter is turned, links connected with said hubs,hooked members connected to said links and adapted to be drawn inward tocontract a rim when a tire is to be removed therefrom or placed thereon,the connection of said hooked members with said links being afforded bythreaded bolts to the heads of which the inner ends of said links areconnected, and tubes slidable in ortions of said casing parts and withwhich tubes said bolts have screw-threaded connections and to the outerends of which tubes said hooked members are swiveled, the hooks on saidhooked members being reversely inclined, as set forth.

5. A tire removing and replacing and tire carrying device comprising asheet metal casing formed in two parts secured together, a shaft mountedin said casin r and having right and left screw-tbreadedvparts, hubs onsaid screw shaftand movable endwise thereof when said shaft is turned,links connected with said hubs, and hooked members connected to saidlinks and adapted to be drawn inward to contract a rim when a tire is tobe removed therefrom or placed thereon.
